The branch I generated the series has some patches of SST and i.MX6 SPI patches I previously worked on and it has some changes in m25p80.c.

From: Bin Meng <bin.meng@windriver.com> This adds the missing SPI support to the `sifive_u` machine in the QEMU mainline. With this series, upstream U-Boot for the SiFive HiFive Unleashed board can boot on QEMU `sifive_u` out of the box. This allows users to develop and test the recommended RISC-V boot flow with a real world use case: ZSBL (in QEMU) loads U-Boot SPL from SD card or SPI flash to L2LIM, then U-Boot SPL loads the payload from SD card or SPI flash that is a combination of OpenSBI fw_dynamic firmware and U-Boot proper. The m25p80 model is updated to support ISSI flash series. A bunch of ssi-sd issues are fixed, and writing to SD card in SPI mode is supported. reST documentation for RISC-V is added. Currently only `sifive_u` machine is documented, but more to come.
